At Auschwitz, Daniel joins a resistance group among the inmates after meeting up with an old friend from Lodz. The other members of the group task Daniel with using his skills as a photographer to take secret pictures of the horrors of camp life, which will then be smuggled out to the approaching Allied troops.

Unfortunately, Daniel doesn't get much of a chance to put his skills to good use because before long he and his father are sent off to another concentration camp: Buchenwald. Once there, they join the resistance movement, which has access to guns as well as radio equipment—which they use to make contact with the Allies. Both Daniel and his father are given guns, and Daniel's father uses his weapon to shoot a German officer.
